Which Olympians gained the most Twitter followers in London?

Fourth-Place Medal ranks the seven Americans (and three international athletes) with the most followers on Twitter, then selected their best tweets from London. A big Olympic thank you to Sports Business Daily for the numbers.

You'd think the Twitter account belonging to the bubbly 17-year-old would be filled with multiple exclamation points and LOLs. You find that more in Phelps' account.

Best tweet (in response to Justin Bieber saying he was a fan): I just DIED. Thank you!

Prediction: Franklin will have the most followers after the Rio 2016 Olympics.

7. McKayla Maroney -- 322,674 (+287,062)

International

1. Usain Bolt -- 1,174,411 (+540,319)

The track king is also the king of Twitter braggadocio. He makes Kanye West seem humble.

Best tweet: Thanks to all my real fans and people who believe in me. I am now a living legend that's for sure.

Following athletes on Twitter is probably the worst part of the medium (for me, at least). Bolt is one of the few must-follows.

2. Tom Daley -- 1,170,866 (+826,234)

Britain's favorite handsome diver

Worst tweet: After giving it my all...you get idiot's sending me this... RT@Rileyy_69: @TomDaley1994 you let your dad down i hope you know that

After Daley and his synchro diving partner failed to medal, the 19-year-old diver demonstrated the downsides of the medium when he retweeted a message from someone invoking the name of Daley's late father. Daley handled the situation with class and will surely have more supportive tweets if he comes through a medal in the platform finals on Saturday.
